Bogging

The act of separating the penile lips, so to make space for the needle of a syringe filled with a liquid of choice to slide into the urethra. The user will then close both penile lips around the syringe and proceed to apply pressure on the stopper. This creates feelings of arousal as the liquid balloons his penis.

"Bro, I couldn't stop bogging last night after I watched hentai."
